Penetrating beams of high energy X-rays can be used to produce 3D images of meso/micro-structure. Since this can be done non destructively it is possible to follow the evolution of structure as a consequence of exposure to corrosive environments, temperature, radiation or applied loads, etc. In this talk I will present examples of situations where we have been able to improve our understanding of failure mechanisms and develop better micromechanical models including:

• The propagation of cracks and crack bridging in continuous metal matrix composites

• Tracking the movement of powder during powder processing to form a green state and finally a fully dense consolidated product

• The evolution of stress corrosion cracks

• The crushing of cellular structures such as bone

• The simulated radio-degradation of nuclear graphite
